Data-Based Program Modification: A Continuous Evaluation System with Computer Software to Facilitate Implementation

Abstract
This paper provides a rationale for and describes a continuous evaluation system, data-based program modification (DBPM), which has demonstrated technical adequacy, logistical feasibility, and instructional effectiveness. Additionally, the paper illustrates the use of DBPM with a case study, and then describes the DBPM software package that stores, summarizes, analyzes, and displays a graph of student performance data.
